CABLE-HANGER.

Specification of Letters Patent.

- Patented se ta, 1919.

To all whom it may concern Be it known that I, CHESTER B. HUGHES, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cab1eHangers, of which the following is a full, clear, cpncise, and exact description, reference being had to the accompanying-drawings, forming a part of this specification. I

My invention relates to cable and pipe hangers and has for. its general ob ect the provision of a practical, inexpensive, and sturdy arrangement'for supporting electrlc cables and pipes.

Specifically one of the features of the present invention is an improvement over the cable hanger disclosed in Patent No.

773,710 issued to I). B. Bronson on November 1, 1904, which forms a simple and inexpensive device, but which has one ob ection in that it. does not provide 'efiicient means for attaching it to a support. By the arrangement of my invention this one objection is eliminated and the advantages deriyed'therefrom more than compensate for the slight additional cost of the device.

Afurther obj ect of the present invention is an improved arrangement of a chain of hangers earned by one or two supports and arranged to support a plurality of cables.

These and other ob ects will be pointed out in connection with the accompanying drawings wherein,

Figure 1 is a side elevational view of the cable hanger of my invention;

Fig. 2 is an end view of Fig. 1 showing the cable and porcelain bushing in section;

Fig. 3 is a view showing the improved chain arrangement of hangers in which the hangers are carried by two supports; and

Fig. 4 is a modified arrangement of Fig. 3 in which only one supporting member is used. I

Similar characters .of reference refer to similar parts throughout the several views.-.

these projections are provided with an aperture, as shown at 10 in- Fig. 1, for the reception of a screw for securing the free ends of the metal strap'together. The side of the circular portion of the strap 6 opposite the opening 7 is provided with an outwardly extending loop 11 whose extreme outer end is flattened as shown at 12. Welded to this flat portion of the loop is a base piece 13 which extends laterally from the hanger to provide the two cars 14 and 15. These ears are provided with openings at 16 and 17 for the reception of screws to facilitate connection of the hanger with asupport. The base piece 13 is spot welded to the loop 11 so that it forms a part of the loop.

v Porcelain bushings are employed at 18 I and l9,'each of whichis substantially semiclrcular in shape and is provided with a groove 19 on its periphery for the reception ofthe metal strap 5. A cable is shown at 20 between the porcelain bushings 1,8 and 19. After the bushings and cable have been put in place, as shown in Fig. 2, a screw is inserted into the openings 10 formed in the projections 8 and 9 so that the free ends of the hanger to be attached to a support having practically any shape or conformation. If the support to which the hanger is attached is convex or concave the base piece 13 can be bent into the required shape very conveniently.

.In Fig. 3 have shown a chain of cable hangers mounted between two supports 21 and 22. The hangers designated at a and b are constructed exactly as is the hanger shown in Figs. 1 and 2. Each one of the intermediate hangers -cc consists of two semi-circular metal straps 23 and 2 1, each of which .is provided at its ends with an outwardly extending projection shown at 25-25. The outwardl extending projections of adjacent cable angers overlap one another, as shown in this figure, and the several hangers are held together by the screws shown at 26.

v In Fig. 4 I have shown a modified arrangement in which only one support is usedythis support being shown at 27. In this case the last conduit hanger away from piece attached to the support may be formed by a complete loop 28 provided at its open end with the projections 29-29 overlapping the projections of the adjacent hanger. The hangers are secured to one another by the screws shown which serve not only to provide a connection between the several hangers, but also as meanswhereby the hangers may be contracted to hold the several cables in place.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. A cable hanger consisting of a metal strap bent into substantially circular form With an opening at one side, the ends of they strap pro ecting outwardly at the sides of the opening, said strap being constructed with an outwardly projecting loop having a substantially fiat portion, a bendable base the flat portion of the loop and extending laterally from the hanger strap projecting outwardly at the sides of the opening, said strap being constructed with an outwardly projecting loop having a substantially flat portion, a bendable base piece welded to the flat portion of the loop and extending laterally from the hanger to form an attaching piece, and means for securing the strap together at the said openlng. p I

' In witness whereof, I hereunto subscribe my name this 30 day of July, 1917.

CHESTER B. HUGHES.
